so here is most likely the final verdict; the stlye of grip on the k hunter is not right for my friends prefered grip. we tried EVERY tip given and then some , and still could not substantialy change the point of impact. the most improvement came from:
nock point-5/8 inch up.
ce heritage 600's cut to 30 1/2 "
200gr head
strike plate built out so far the arrow barely laid on the rest!
still grouping 4-5 inches from center.
maybe it's the bow - maybe it's the loose nut behind the bow -but  he's decided it's not the bow for him.- keep your eyes out boys this bow may be a st. judes item.
thanks for all the advice-much appreciated.
